Louis BROUSSAS, OF LYONS, FRANCE.

PROCESS OF CONNECTING T-IRONS.

SPECIFICATION forming part of Letters Patent No. 650,299, dated May 22, I900.

" Applicationfiled May 9,1898. Serlalllo. 680,203. (No model.)

' To all whom, it nmg co wernr Be it known that I, LOUIS BROUSSAS, a citizen of the Republic of France, residing at Lyons, France, have invented certain new and useful Improvements in Building Structures, of which the following is a specification.

This invention relates to materials designed particularly for building or erecting bridges, but useful also in the manufacture of columns, beams or girders, and other objects.

The chief object of my invention is to provide a new and improved building structure possessing such characteristics that While composed of cement or agglomerant and ironparts it is strong, substantial, durable,- and capable of successfully resisting excessive shocks, pressures, and strains. This object is accomplished in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a view, partly in elevation and partly in section, of a post constructed in accordance with my invention. Fig. 2 represents a horizontal section through the same post, showing the arrangement of the T-irons. Figs. 3 and 4 each illustrate a different means of connecting at intervals the T-irons one with the other. Figs. 5, 6, 7, and 8 show different forms of posts or pillars and also the devices for connecting the T-irons one with the other which may be employed according to various applications of my invention. Figs. 9 and 10 illustrate the application of my invention to a factory chimney-shaft. Fig. 11 shows the invention applied to the principal rafters of trusses and to columns. Figs. 12 and 13 represent the application of the invention to a concrete tile or slab for roofing.

Similar letters of reference indicate corresponding parts in all the figures of the drawlugs.

As shown in Figs. 1 and 2, a post or column constructed in accordance with my invention consists of four T- irons A A A A, serving as an external casing or protection and forming flattened angles, the webs or flanges of such T- irons being embedded in the cast mass or agglomerant substance B. These T- irons A, which at the same time serve to protect the posts against shocks, are connected one with the other at intervals by their flange either by means of iron wires 0 C, which are bent at their extremities, or by means of small bands of stamped iron, which serve the same purpose. In order to facilitate the assembling of these irons A to insure their being separated by exactly similar intervals pre vious to their connection and also in order to impart a still greater degree of cohesion to the mass, a series of plates D, (see Fig. 8,) having their angles out out so as to form a bearing for the flanges of the T- irons, may advantageously be arranged at intervals in the pillar or column. In pillars of large section the plates D may be replaced (see Fig. 4) by a series of cross-pieces E with notched extremities and serving to connect the T- irons one with the other with great rigidity.

When the T-irons have been arranged in the desired positions, according to the size of the pillar or column to be constantly and rigidly connected one with theother, the agglomerant substance is castdirectly within them and consolidated in the usual manner while temporarily retained by means of I graphic lines, for example, they may be cast with their insulating substance direct. To the top of these posts may be appliedany desired ornamentation-of the kind illustrated in Fig. 1, for example. They may likewise receive the collars or supports necessary for the applications for which they are intended. Instead of being made solid these posts may equally well be cast hollow, as shown in Figs. 5,6, 7, and 8. In this case the flanges of the T-irons instead of being united diagonally by the iron bands or wires 0 are connected directly with the flanges adjacent to them, either with or without the use of iron frames F, (see Fig. 6,) fulfilling the ofiice of the plates D and of the cross-pieces E. The frames F are arranged at intervals along the post and already described and also with the irons A as a whole by means of iron wires or connections 0 and suitable bearing-frames F; 'In order to give still greater rigidity to the pillar, these two series of single T-ironsm-aybe replaced by a single series'of double T-irons' connected one with the other in the manner above described. f i Factory chimney-shafts may also be con-' structed in accordance with my invention in the manner illustrated in Figs. 9 and 10, for example, either by means of a cast agglomerant substance; or of bricks. In thisapplication to chimney-shafts the frames F are replaced by notched or indented iron' hoops G, (see Fig. 10,) which being engaged and v 7 It will be observed that in the different connected with each of the flanges of the T- irons' and being embedded in the massat intervalsimp'art complete cohesion to the Fig.1l.

" cording to thewpitch of the rafter.

" other in the manner already described. As

regards the columns to which these rafters are attached they are likewise formed of an agglomerant substance cast between the two T-irons, M M and are connected with the rafters by means of fish-plates or cheeks N.

' Therafters are connected one with the other at the ridge of the roof by means of other fish-plates I. Finally, the roofing consists. of

slabs or tiles, which are also formed by cast:

ing the desired agglomerant substance in an iron frame, (see Figs. .12 and 13,) two opposite sides of which are formed by small T- irons A A, the other two opposite sides consistingof angle-irons P .P. In order to impart a greater degree .of. consistency to the slab, a bar 0, which is fixed at both extremities to the angle-irons, is embedded in the thickness of the plate and likewise serves as an intermediate connection between the iron wires O.

The T-irons above referred to may be employed either in/the rough or nickeled, bronzed, or galvanized; They may also be of the ordinary form or slightly molded or fluted .in order to produce a more decorative effect. v

. Finally, my invention is equally capable of application to a multiplicity of other'purposes-such, for example, as theconstruction of the arch-stones or voussoirs of bridges, the

coping of walls, timber summers, conduitpipes, vats, reservoirs, gasometers,the spires of edifices, &c.

forms of my invention the T-shaped irons or columns have their faces presented outward and their webs projecting inward, all being embedded in the plastic or agglomerant substance. This arrangement of the T-shaped irons or columns enables the structure to sue cessfully resistor withstand excessive shocks and pressures.

.What I claim is 1 A building structure, consisting of a mass of plastic material or agglomerant,a plurality of T-shaped irons spaced apart, embedded "in the plastic mass oragglomerant and having their faces presented outwardand their webs projecting inward, and tie-wires con* necting the inwardly-projecting web'sof the T-shaped irons and also embedded in the plastic mass or agglomerant, substantially as and for the purpose described. f

In testimony whereof I have hereunto set my hand, in presence of two subscribingwitnesses, this 28th day of April, 1898.
